Cardiac muscle
Cardiac muscle is a specialized type of muscle found only in the heart. It is responsible for pumping blood throughout the body, ensuring that organs receive the oxygen and nutrients they need. Unlike skeletal muscle, which we control voluntarily, cardiac muscle operates involuntarily, meaning it functions automatically without conscious effort. This muscle has a unique structure that allows it to contract rhythmically and continuously throughout a person’s life. Its cells are interconnected, enabling efficient communication and coordination, which is crucial for maintaining a steady heartbeat and overall cardiovascular health.

Cardiac muscle is a specialized type of muscle found only in the heart. It is responsible for pumping blood throughout the body, ensuring that oxygen and nutrients reach all tissues. Unlike skeletal muscle, which we control voluntarily, cardiac muscle operates involuntarily, meaning it functions automatically without conscious thought. This muscle is unique in that its cells are interconnected, allowing for coordinated contractions. Cardiac muscle is also highly resistant to fatigue, enabling it to beat continuously throughout a person's life. Proper function of cardiac muscle is vital for overall cardiovascular health.

Cardiac muscle is a specialized type of muscle tissue found in the heart. Unlike skeletal muscle, which we control consciously, cardiac muscle works automatically and continuously to pump blood throughout the body. It consists of interlinked cells that allow for synchronized contractions, ensuring that the heart beats rhythmically. This muscle is resilient and can adapt to the body’s changing demands for oxygen and nutrients. Cardiac muscle cells have a unique property called automaticity, meaning they can generate their own electrical impulses, triggering heartbeats without external signals. This is crucial for maintaining a steady blood flow.
